Display device location

This code sample is available for these platforms:
View Sample on GitHub

Display your current position on the map, as well as switch between different types of auto pan Modes.


Use case

When using a map within a GIS, it may be helpful for a user to know their own location within a map, whether that's to aid the user's navigation or to provide an easy means of identifying/collecting geospatial information at their location.

How to use the sample

Tap the button in the lower right (which starts in Stop mode). A menu will appear with the following options:

  • Stop - Stops the location display.
  • On - Starts the location display with no AutoPanMode mode set.
  • Re-Center - Starts the location display with AutoPanMode set to Recenter.
  • Navigation - Starts the location display with AutoPanMode set to Navigation.
  • Compass - Starts the location display with AutoPanMode set to CompassNavigation.

How it works

  1. Create a MapView.
  2. Get the LocationDisplay object by calling getLocationDisplay() on the map view.
  3. Use start() and stop() on the LocationDisplay object as necessary.

Relevant API

  • Map
  • LocationDisplay
  • LocationDisplay.AutoPanMode
  • MapView

Additional information

Location permissions are required for this sample.
